Study on Well-Kill Calculation Model with Deep-Water Engineers Method
With the growing demand for oil and gas resources of China,exploration and development face more complex situation and there is an urgent need to move to (deeper than 1000m) deep sea oil and gas exploration and development.As the density window for safe drilling fluid is narrow,the mud line is in high pressure and low temperature environment,and the cycle pressure loss in choker line is larger and other characteristics,Well-kill calculation model with deep-water engineers method is disparate with that for land.To this end,combined with the special formation conditions in deep water well control and the characteristics of long choke line,on the basis of considering the impact of the friction of choker line,gas compressibility factor,temperature and other parameters on the casing pressure and stand-pipe pressure,well-kill pressure parameters (including stand-pipe pressure,casing pressure,maximum casing pressure,etc.) calculation model of deep-water engineers method is established to carry out example calculation,which has directive significance for on-site well-kill construction.
